This is so colourful. I'm going to have to google this particular critter--like some of your others--to see what the real world version looks like and for more info about it! (and back to add... they have an amazing pattern!)

They are amazing looking. The person who commissioned this says that they're even brighter immediately after a molt! But because they start fading straight away, almost all the google images don't do justice to their vividity.
